Abstract: The present disclosure provides an electronic device including a substrate, an extending element, a conductive element and a first insulating layer. The substrate includes an edge. The extending element is disposed on the substrate and includes a first conductive layer and a semiconductor layer, the first conductive layer and the semiconductor layer are overlapped, and the semiconductor layer extends to the edge of the substrate. The conductive element is overlapped with the first conductive layer. The insulating layer is disposed between the conductive element and the extending element.

Abstract: A storage/retrieval device for optical disks includes a container having an access slot. A disk shelf is rotatably mounted in the container and includes a plurality of storage compartments each for receiving an optical disk. A driving roller and a driven roller are rotatably mounted in the container for moving an optical disk into or out of the container via the access slot. An ejecting member includes a first end pivotably supported in the container and a second end operably coupled with the driving roller. The ejecting member is pivotable between a first position in one of the storage compartments for moving an optical disk in the storage compartment out of the storage compartment and a second position outside the storage compartment. A motor is provided to drive the driving roller for rotating the driving roller and the driven roller in opposite directions and for pivoting the ejecting member.

Abstract: An optical disc storage/retrieval apparatus includes a vertically extending casing, a fixed frame mounted in the casing, an elevating platform mounted on the fixed frame and slidable in a vertical direction relative to the fixed frame, and a sliding seat mounted on the elevating platform and movable in a forward/backward direction relative to the elevating platform. The sliding seat includes a fixed lower clamping member and a movable upper clamping member pivotally mounted to the sliding seat. The casing includes an access and a plurality of vertically spaced storage compartments for storage of optical discs. A control/display device is mounted on a surface of the casing for controlling vertical movement of the elevating platform, movement of the sliding seat in the forward/backward direction, and movement of the movable upper clamping member.

Abstract: A storage/retrieval device for optical disk comprises a casing and a disk shelf rotatably mounted in the casing, the disk shelf comprising plural storage grooves each for receiving an optical disk. An ejecting/placing mechanism is mounted in the casing for proceeding with storage/retrieval of the optical disk. A control/display device is operably connected to a drive device for driving the disk shelf to turn. The control/display device comprises a detecting circuit for detecting a position of an associated one of the storage grooves of the disk shelf for receiving the optical disk to be stored/retrieved. The optical disk is automatically ejected out of the casing via a window in the casing from the associated one of the storage grooves of the disk shelf or placed into the associated one of the storage grooves of the disk shelf upon opening of the window of the casing.
